Watercraft Changes at LAK Reservoir Near Newcastle

The threat of an introduction of invasive aquatic species into LAK Reservoir near Newcastle has resulted in changes to recreational access to the site. As of April 1, motorized watercraft, including watercraft with electric motors, are not allowed on LAK Reservoir. Non-motorized watercraft that are hand-launched will still be allowed. In addition to these watercraft, the reservoir will remain open to anglers for shore and ice fishing. Sheridan Region Fisheries Supervisor Paul Mavrakis said due to the discovery of invasive zebra mussels in Pactola Reservoir in South Dakota last summer, the threat of these invasive species getting introduced into Wyoming water has been significantly increased. Mavrakis added that in discussions with True Ranches, it was decided that eliminating motorized watercraft on the reservoir would be an effective way to help reduce the AIS threat to the reservoir while still providing access to anglers.

LAK Reservoir is privately owned by True Ranches. Public access to it is provided by an access agreement between the ranch and the Wyoming Game and Fish Department.  All watercraft traveling into Wyoming from out of state between March 1 through November 30 must be inspected prior to launching on a Wyoming water. In addition, any watercraft that has been in a water infested with zebra/quagga mussels within the last 30 days, is required to undergo a mandatory inspection by an authorized inspector prior to launching in Wyoming anytime throughout the year. Resident and nonresident watercraft owners must also purchase and display a valid AIS decal. Only non-motorized inflatable watercraft 10 feet or less in length, solid and inflatable paddleboards regardless of length, and devices defined as water sport toys are exempt from the decal requirement.
